Answer 1

What are you solving for?

Answer 2

theoretically, you could solve for either x or y, or for x^2 or y^2.
But this equation is the general form of the equation of an ellipse centered at (0,0).

Aren't there any further instructions?

Answer 3

X

Answer 4

solve for x?

Answer 5

subtract y^2/b^2 from both sides

multiply by a^2

then take the square root of the whole expression
